The mainboard provides a Slot-1 for Pentium II/III processor. The CPU on board must
have a fan or heat sink attached to prevent overheating.
WARNING: Without a fan or heat sink, the CPU will overheat and cause damage to both the CPU
and the mainboard.
To install a CPU, first turn off your system and remove its cover. Locate the Slot- 1 and place
RETENTION MODULE as following:
IMPORTANT: You must set jumper U19,U20 for “Bus Frequency Selection” and “CPU Ratio” on
page6
depending on the CPU that you install.
1. Attach heat sink to the CPU.
2. Place Part A on Slot-1 and gently screw four corners on top of the main- board.

The mainboard also provides a 370-pin ZIF Socket 370. The CPU on mainboard must
have a fan attached to prevent overheating.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF Socket and
open it by first pulling the lever sideways away from the socket then upwards to a 90-degree
